Abstract
BACKGROUND Genetically engineered T-cell immunotherapies for adoptive cell transfer (ACT) have emerged as a promising form of cancer treatment, but many of these patients develop recurrent disease. Furthermore, delineating mechanisms of resistance may be challenging since the analysis of bulk tumor profiling can be complicated by spatial heterogeneity. METHODS Tumor samples were collected from a patient with synovial sarcoma who developed acquired resistance to ACT targeting NY-ESO-1. Biopsies (primary, progressive metastasis, and recurrence) were subjected to bulk tumor DNA and RNA sequencing, as well as high-dimensional spatial profiling of RNA and protein targets. Untreated and progressive lesions were compared with identified patterns associated with acquired resistance to ACT. RESULTS Gene expression patterns due to immune activity and infiltration were diluted in bulk tumor sequencing. The metastasis was enriched for tumor regions with increased CTNNB1 (encoding beta-catenin), which were negatively associated with the expression of T-cell surface proteins and antigen presentation machinery. Spatial profiling was most highly concordant with bulk sequencing in the lesions with decreased spatial heterogeneity. CONCLUSIONS Complementary use of bulk and spatial profiling enables more accurate interrogation of tumor specimens, particularly to address complex questions regarding immunotherapeutic mechanisms. Our study uses this approach to demonstrate a mechanism of T-cell exclusion and resistance to cellular immunotherapy in synovial sarcoma.

Front Oncol 2021; 11:762288. [PMID: 34881180 PMCID: PMC8648074 DOI: 10.3389/fonc.2021.762288] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2021] [Accepted: 10/28/2021] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Doxorubicin/Adriamycin (ADM) alone or combined with ifosfamide (IFO) (AI) is available for previously untreated advanced soft tissue sarcoma (ASTS). However, the clinical choice between them remains controversial. In this pooled analysis, we comprehensively compared the efficacy and tolerability of AI versus ADM in patients with ASTS. METHODS PubMed, Web of Science, EMBASE, and Cochrane Library were systematically searched from inception to April 14, 2021. Eligible studies were randomized clinical trials comparing AI to ADM. The primary outcomes were overall survival (OS), progression-free survival (PFS), and objective response rate (ORR). Discontinuation rate (DR) and toxic death (TD) were explored as secondary outcomes. RESULTS Overall, three open-label randomized phase 2/3 clinical trials with a total of 1108 newly diagnosed ASTS patients were enrolled. Between AI and ADM, pooled hazard ratios were 0.93 (95% confidence interval 0.58-1.50, p = 0.78) for OS and 0.85 (0.57-1.25, p = 0.41) for PFS. While pooled risk ratios for ORR, DR, and TD were 1.37 (0.94-1.99, p = 0.10), 1.04 (0.74-1.46, p = 0.82), and 0.68 (0.19-2.36, p = 0.54) respectively. No publication bias was observed across the studies. CONCLUSION In the first-line setting, adding IFO to ADM failed to benefit ASTS patients against ADM alone, even with comparable tolerability.

Abstract
INTRODUCTION The aim of this study was to describe patient characteristics, treatment, and oncologic outcomes of soft-tissue sarcomas (STSs) of the hand. METHODS Sixty-nine STSs of the hand in adult patients treated at a tertiary referral center were retrospectively included. We describe patient and tumor characteristics along with oncologic outcomes. RESULTS Epithelioid sarcoma (23%) was the most common histologic subtype, followed by synovial sarcoma (15%). Of all tumors, 17 (25%) were grade I, 22 (32%) were grade II, and 30 (44%) were grade III. The 5-year disease-free survival for epithelioid sarcomas was 75% with a disease survival of 100%, along with a metastatic rate of 15%. Of the patients with a synovial sarcoma, 40% developed metastases, and the 5-year disease-free survival was 68% and the 5-year disease survival was 73%. CONCLUSION Hand STSs are aggressive tumors with a high metastatic potential. Even with adequate oncologic treatment, long-term clinical follow-up (10 years) in these tumors is advised. The treating surgical oncologist should not be deceived by their smaller size.

Abstract
Background: Synovial sarcoma (SS) is a rare, aggressive soft tissue sarcoma with a poor prognosis after metastasis. The objective of this study was to conduct a systematic review of the clinical evidence for therapeutic options for adults with metastatic or advanced SS. Materials & methods: Relevant databases were searched with predefined keywords. Results: Thirty-nine publications reported clinical data for systemic treatment and other interventions. Data on survival outcomes varied but were generally poor (progression-free survival: 1.0-7.7 months; overall survival: 6.7-29.2 months) for adults with metastatic and advanced SS. A high frequency of neutropenia with systemic treatment and low quality of life post-progression were reported. Conclusion: Reported evidence suggests poor outcomes in adults with metastatic and advanced SS and the need for the development of new treatment modalities.

Abstract
Sarcomas are an unusual group of tumors, accounting for ~1% of cancer in adults. Immunotherapy has been shown to be a potential therapeutic option for the management of patients with cancer. However, there is still insufficient information on the action of immunotherapy on sarcomas. A 16-year-old male patient, diagnosed in December 2013 with grade III soft-tissue sarcoma in the right arm, was admitted to a private oncology service after relapse following surgical treatment. The patient underwent chemotherapy with ifosfamide plus adriamycin for 4 cycles, associated with adjuvant radiotherapy, followed by a new resection to remove the residual lesion. A year later, imaging tests identified pulmonary micronodules, and a new resection was performed. After immunohistochemical evaluation of biopsy, a large presence of programmed cell death 1 ligand 1 (PD-L1) marker was identified in tumor tissue and immunotherapy with nivolumab was performed. At present, the patient is in immunotherapeutic treatment (42 cycles), presenting an excellent general condition and without any symptoms, and a decrease in neoplastic lung masses. The literature recommends three cycles of anthracycline plus ifosfamide as adjuvant therapy to surgical treatment. Combined surgery plus adjuvant therapy has shown benefits in malignant tumors. Immunotherapy is an important therapeutic option for soft-tissue sarcomas with high programmed cell death protein 1 (PD-1)/PD-L1 expression. Treatment for high grade soft tissue sarcoma (STS) is still limited, due to tumor heterogeneity, and further studies are needed to consolidate the possibility of using immunotherapy to treat these neoplasms. When significant levels of specific biomarkers are present in tumor tissue, immunotherapy may be beneficial as shown by the present case report.

Abstract
Soft tissue sarcoma (STS) of the extremities are a rare tumor. Metastases develop in about 40%-50% of patients, most of whom die from their disease. We sought to identify potential risk factors associated with metastatic diseases upon presentation for patients with STS and established a reliable nomogram model to predict distant metastasis of STS at presentation. The current study retrospectively analyzed 3884 STS of the extremities or trunk patients from the Surveillance, Epidemiology, and End Results (SEER) database between 2010 and 2015. Based on patient registration, all patients were randomly allocated to training sets and validation sets (2:1). Then, univariate and binary logistic regression analysis was used to determine the significantly correlated predictors of metastasis. Finally, the nomogram model was established, using these predictors and validated it. 311 (8.21%) of the cases experienced distant metastatic disease was present at the time of presentation. The nomogram was developed from age, histology subtype, primary site, tumor size, grade and depth. Encouragingly, the nomogram showed favorable calibration with C-index 0.790 in the training set and 0.801 in validation set. The DCA showed that the novel model was clinically useful. This nomogram model had a high precision to predict the metastasis of soft tissue sarcoma of the extremities. We expect this model could be used in different clinical consultation and established risk assessment.

Abstract
Abstract
Background: Synovial sarcoma represents 8% of all soft-tissue sarcoma (STS). It is a high-grade STS, and 50% of patients develop metastasis. The most common site of metastasis is the lungs, lymph nodes followed by bones. Ifosfamide-based chemotherapy is associated with improved outcome. In this study, we report our experience of metastatic synovial sarcoma according to primary sites, metastatic pattern, and their outcome. Materials and Methods: This was a retrospective observational study carried out at our institute from January 2013 to December 2016. The aim of our study was to evaluate the pattern of metastasis, response to chemotherapy, and survival in patients with metastatic synovial sarcoma. Results: Over a period of 4 years, 43 patients with metastatic synovial sarcoma were diagnosed with median age of 30 years. Nearly 70% of patients had lung metastasis, other site of metastasis were lymph node, bone, and liver. Thirty patients received chemotherapy with a combination of ifosfamide and doxorubicin. The overall response rate was 87% with median progression-free survival of 8 months. Patients with lung only metastasis had better survival compared with nonpulmonary metastatic site (18 months vs. 12 months). The median survival was 18 months. Conclusion: Metastatic synovial sarcoma is chemoresponsive tumor with lung being the most common metastatic site. Patients with lung only metastasis had a better outcome than nonpulmonary metastasis.

Abstract
Synovial sarcoma is a rare soft tissue sarcoma characterized by a t(X;18) translocation, which results in a SYT-SSX gene fusion. In the metastatic setting, chemotherapy has limited, durable efficacy prompting the necessity for new therapeutic modalities. One emerging new strategy involves T-cell-directed therapy such as tumor-infiltrating lymphocytes or the development of T cells that are genetically engineered to express a T-cell receptor against a cancer testis antigen. Of these approaches, engineered T cells that recognize NY-ESO-1 are the furthest along in development. Completed and on-going clinical trials have shown promise and there are efforts to continue to optimize the current approach.

Abstract
Synovial sarcoma (SS) is an aggressive soft tissue sarcoma (STS) that typically occurs in the extremities near a joint. Metastatic disease is common and usually occurs in the lungs and lymph nodes. Surgical management is the mainstay of treatment with chemotherapy and radiation typically used as adjuvant treatment. Although chemotherapy has a positive impact on survival, the prognosis is poor if metastatic disease occurs. The biology of sarcoma invasion and metastasis remain poorly understood. Chromosomal translocation with fusion of the SYT and SSX genes has been described and is currently used as a diagnostic marker, although the full impact of the fusion is unknown. Multiple biomarkers have been found to be associated with SS and are currently under investigation regarding their pathways and mechanisms of action. Further research is needed in order to develop better diagnostic screening tools and understanding of tumor behavior. Development of targeted therapies that reduce metastatic events in SS, would dramatically improve patient prognosis.

Abstract
INTRODUCTION Previous studies in metastatic soft tissue sarcomas (STS) showed that synovial sarcomas tend to have better survival rates and a higher chemosensitivity than other STS subtypes. However, data are derived from relatively small subgroups and statistical significance of these observations is lacking. Larger cohorts are necessary to define and confirm the specific characteristics of this subtype. PATIENTS AND METHODS Patient data were retrieved from 15 European Organisation for Research and Treatment of Cancer advanced first-line STS trials. Patient characteristics, survival and treatment response of synovial sarcoma patients were compared to other STS patients. Univariable and multivariable analyses were performed to evaluate prognostic factors. RESULTS In total, 3330 advanced STS patients were retrieved, of whom 313 had a synovial sarcoma. Synovial sarcoma patients were significantly younger (median 40 versus 52 years), more often had extremity primary tumours and had a better performance status (PS 0: 50.2 versus 43.4%) compared to other STS patients. Additionally, synovial sarcoma patients had a significantly better response to chemotherapy (responders: 27.8 versus 18.8%) and better survival rates (progression free survival [PFS]: 6.3 versus 3.7 months; Overall survival [OS]: 15.0 versus 11.7 months). Age, PS, and presence of metastatic disease were defined as prognostic factors for PFS and OS in the univariable analysis. The last two factors were confirmed in the multivariable analysis for OS. DISCUSSION Advanced synovial sarcomas are a distinct subgroup of STS, with a better response to systemic chemotherapy and longer PFS and OS. These results should be taken into account in the design of future synovial sarcoma specific studies.
